resume on Exception

All, I know I can trap and exit on an exception but how can the program
trap and continue?

say I have

while <condition>

update xxx where recnum ... ;
if any_exception then
write any_exception & recnum to file and continue;
end if;

end loop;

any examples of this logic?

Thanks!
Bob
